Nitrogenous contaminants such as ammonia and nitrite have been found to appear frequently in the source water used for coastal aquaculture (Krishnani et al., 2002; Krishnani et al., 2003). Presence of excessive nitrogenous compounds in source water may cause eutrophication in the receiving water aquaculture ponds. Ammonia is the major end product of protein catabolism, which remains in the form of unionized ammonia (NH3) and ionized ammonia (NH4 +). The proportion of unionized and ionized ammonia varies with pH and temperature. Unionized ammonia is a critical water quality parameter and toxic to aquatic life, but the ammonium ion is harmless except in extremely high concentrations. The problem of keeping the undissociated ammonia concentration within non-harmful limits is reduced, in practice, to control over the total ammonia concentration. Nitrite is an intermediate product in bacterial nitrification and denitrification processes. Therefore, the reduction of the impact of total ammonia and nitrite on the receiving environment may be essentially obtained upstream by optimizing shrimp/fish farming management practices regarding feeding and water quality (Porrello et al., 2003).
